BBB: Add sd_setup.sh to create a bootable SD and README to document SD and UART booting
sd_setup.sh is a script that automates the process of setting up
an SD card with the appropriate uMon image to boot using either
"raw" or FAT mode.
README currently documents the steps required to boot the
Beaglebone Black from an SD card or via UART.

BBB: Build an MLO file when booting from non-XIP devices (e.g. SD)
An MLO file will be created from the concatenation of a corresponding GP header
and the uMon image. A GP header must be prepended to the uMon image when
booting from non-XIP devices. Refer to the AM335x TRM, Section 26.1.9 for more
information.
These type of images have been tested when booting the MLO file from an SD card
with a FAT32 primary partition marked as Active.

score: Add potpourri lock statistics
These SMP lock statistics are used for all lock objects that lack a
storage space for the statistics. Examples are lock objects used in
external libraries which are independent of the actual RTEMS build
configuration.
